    Default Qtopia install

    Hello anybody,

    I'am using FC4
    I have douwnload qtopia core opensource tar.gz
    i have unpacked it and compile it with ./configure -embedded x86
    Compiling no problem.
    I set my path to /usr/local/Trolltech/QtopiaCore-4.1
    When i try to start qtopia designer a error popping up see error
    WSSocket::connectToLocalFile connection refused : Verbinding geweigerd
    QAbstractSocket::waitForReadyRead() is not allowed in UnconnectedState
    QAbstractSocket::waitForReadyRead() is not allowed in UnconnectedState

    No Qtopia Core server appears to be running.
    If you want to run this program as a server,
    add the "-qws" command-line option.

    I have read in the install that qtopia needs to run on Linux Framebuffer or Virtual Qtopia Core Framebuffer.
    Must i recompile the kernel to set the framebuffer or can i set the framebuffer in /etc directory or somewhere else.

    I think you have to install Qt/Desktop too. It comes with the framebuffer emulator. The framebuffer emulator ist desktop application and the framebuffer is the part in the window. Once you have compiled Qt/Desktop, start qvfb. It is located either in the bin-dir of Qt/desktop or in tools. Then start your Qtopia app using paramteters -qws -display QVFb:0

    I think it does not make sense to start the designer in the framebuffer because you can also use the designer from your Qt/Desktop installation.

    Dear axeljaeger

    I have also Qt-4.1.0-rc1 before i compiled QtopiaCore.
    I search for qvfb in Qt-4.1.0-rc1 in the bin-dir and in other direktory's on the system but no qvfb file found.

    Only in the QtopiaCore-opensource-src-4.1.0 in the /tmp i have found in tools qvfb file.
    Where can i find the qvfb file.

    Documentation from Trolltech says that it should be located in $QTDIR/tools:

    http://doc.trolltech.com/4.1/emb-qvfb.html

    Do you have such a directory in either Qt installation and what are contents of these?

    I have look in Qt-4.1.0-rc1 direktory no direktory /tools

    I 'am now making a new installation of Qt-4.1.0 its compiling now.
    If i look at the compiling result in the console so far i see that Qt must make a directory called tools.
    If the compiling is finished there no direktory called /tools in my /usr/local/Trolltech/Qt-4.1.0.
    Is this a bug?

    Not in /usr/local/Trolltech/whatever but the directory you unpacked the source. Also have a look wether there is a similar directory in the sourcetree of Qtopia Core.

    Yes there is in /tmp directory where i unpacked the Qt-4.1.0 a directory /tools with qvfb.
    If i compile Qt-4.1.0 then the qvfb will automatic compile with in it ?.

    Which Qt is your Qt 4.1? Desktop or embedded (Qtopia core). Where in the sourcetree did you found that qvfb-thing? I doubt there is a file /tmp/qvfb.cpp on your harddisk. The thing is: There is a driver for qvfb and there is qvfb itself. I don't know to which that files belong you found. The trolltech doc I gave you mentioned a flag -qvfb that you should pass to ./cofigure.

    Qt-4.1.0 Desktop Edition ( qt-x11-opensource-src-4.1.0).
    I have unpacked in /tmp/qt-x11-opensource-src-4.0.1
    In the qt-x11-opensource-src-4.0.1 there is a directory /tools/qvfb
    I have compiled the qt-x11-opensource-src-4.0.1 with ./configure -qvfb
    thus with -qvfb flag.

    You might have to manually compile qvfb. Remember to use x11 to do it.

    Thanks axeljaeger for your time and answers.

    The problem off qvfb is solved.
    The compiling off Qt-4.1.0 Desktop Edition don't compile qvfb automaticly.
    If i start ./configure -qvfb than compiler look first to the pro.files and he find also qvfb.pro.
    When i start gmake or make than the compiler don't compile the qvfb.pro file but the rest off tools direktory he compile's.

    I have manually compile the qvfb. in the /tmp/qt-x11-opensource-src-4.1.0/tools/qvfb.
    I copied the excutable *qvfb to the /usr/local/Trolltech/Qt-4.1.0/bin direktory.
    It works now fine
    Also thanks for Ipotter.

    Hi,

    I think the Qtopia article on http://www.linuxdevices.com/articles/AT7319394180.html may be helpful in this discussion.

    This popular white paper is written by some engineering folks from our organization Mindfire Solutions (http://www.mindfiresolutions.com).

    I hope you find it useful!

    Cheers,
    Byapti
